I can't find the instructions for my electric ice cream machine. It's been a few years since I used it. Can you help me? Unlike those really cool gelato machines, my little maker has no computer. Just an On/Off switch. It has a main section that you freeze overnight. Then you add chilled ice cream ingredients and place the paddle and motor on it. Then hit the On button. What comes next is what I don't remember. I've googled and every site I've found says "follow manufacturer's directions." Arrrrgh. How do I know when to turn the machine off? Thanks for your help!
